They are real, at least some are. I don't believe this one I serviced was a redial:
Hi Archer! I'm very new here so please forgive na茂vet茅 of this question. Did you mention that this particular dial can still be ordered from Omega? Is that true for the lady's version as well? If so, does one have to send the watch to them for service?
Also, Omega made a similar one to the above with orange markers on a dark grey background that you can still buy brand new from Omega, so they did certainly make them in racing dial format with orange markers.
